Abstract: ABSTRACT It is known to extract oil from oil sands or oil shale deposits by high temperature, high pressure steam treatment.  Such processes consume a significant proportion of the produced oil to generate the required steam. This lowers the efficiency of recovery.  The present invention seeks to over-come this drawback by providing a process for the production of petroleum from oil sand or petroleum containing rock which comprises:  adding cyclo-dextrin or a starch decomposition product containing cyclodextrin to the oil sand or oil containing rock to form a cyclodextrin oil inclusion compound; separating the resulting petroleum inclusion compound from the oil sand or oil containing rock, and treating the resulting oil inclusion compound with hot water or steam to separate the petroleum from the cyclodextrin or starch decomposition product containing dextrin.

Abstract: Abstract The invention relates to a process for monitoring tank interior cleaners driven by a cleaning agent, that have a rotating body that forms part of the supply path and which have at least one output nozzle, and which indicate the completion of each complete revolution of the rotating body. The rotation time of the rotating body for each full revolution is monitored so that this is represented in the time interval between two voltage pulses, in which connection the final voltage pulse serves as a reset pulse for the monitoring time resulting from the demand for an adequate cleaning effect, this being greater by an adjustable percentage amount than the nominal time for a revolution of the rotating body, and in that for the case that the rotation time is greater than the monitoring time, an electrical and/or visual malfunction signal will be initiated.

Abstract: ABSTRACT OF THE DISCLOSURE Disclosed is a passive infrared intrusion detector including a lamp for locating the zones being protected by the detector.  The detector includes a heat sensor, a lens system for receiving and focusing the body heat of an in-truder on the heat sensor, and electrical circuitry responsive to the heat sensor for actuating an alarm or detection signal when the body heat of an intruder is detected.  The zone locator lamp is positioned near the heat sensor and its light passes through a lens in the general direction of a zone to be protected.  The light parallels a portion of radiation which is focused on the heat sensor by another lens.  If the light can be observed from a given position in front of the detector, that position is in a zone being observed by the detector and body heat radiated from that zone will be focused on the heat sensor.  Thus, zones protected by the intrusion detector can be established by adjusting the position of the detector until light from the zone locator lamp is observed.  Once these zones are established, the lamp may be disconnected and the intrusion detector placed in the "ready" or "stand by" mode.
